2. the equilibrium constant kp for the reaction pcl5(g) ⇌ pcl3(g) + cl2(g) is 1.05 atm at 250ºc. the reaction starts with a mixture of pcl5, pcl3, and cl2 at pressures 0.177 atm, 0.223 atm, and 0.111 atm, respectively, at 250ºc. when the mixture comes to equilibrium at that temperature, which pressures will have decreased and which will have increased? explain why.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
